Further to this previous post, the above is from X-Men: Days of Future Past, the time travel story published in 1980 that the next movie will be based on. In the comic, the far-flung future is 2013, and the present is 1980. The upcoming movie will feature the prequel cast (set in the 1960s) and some of the cast from the 2000-2006 movies. It'll be interesting to see how it all plays out.
